(PDF) BULK FLOTATION OF COMPLEX COPPER ORE Khmer Lee

The flotation of complex sulfide copper ores Complex ore are often characterized by particularly fine intergrowth of the mineral values. Due to this specific mineralogical characteristic, it is necessary to finely grind and concentrate ore prior to the solubilization of valuable metals (Makita, et.al. 2010).

In this paper, the flotation behaviour of nickel-copper ores processed in the Sudbury area is discusse~ with emphasis on the effect of oxidation on individual minerals, pnmarily pyrrhOlite. In general, moderate oxidation of a freshly ground ore promotes the flotability of all principal sulphides in the ore leading to a bulk flotation concentrate.

EVALUATION OF ORGANIC CARBON SEPARATION FROM

The presence of shale, the source of carbonaceous matter in the ore, has also a negative effect on flotation and pyrometallurgical processes. The presence of clay minerals and organic carbon in shale makes the production of high quality flotation concentrates, without excessive loss of copper and other metals in the flotation tailing, difficult.
